Table 3 Breakdown of percentage of correct answers for each question across conditions. Questions 5 and 6 had multiple correct answers, so percentages correspond to those who responded with all and only the correct answers. P values correspond to chi-square tests for discrete measures and ANOVA for the continuous measures. No simple comparison was made for the ordinal measures
